This fan is very suitable for electric vehicle heat dissipation transformation, 48V~60V can be used directly,(60V stable operation, and the air volume is larger than 48V)In addition, the motor is fully waterproof, and the air volume is super large.
note:The fan is very very violentDuring the test, please be careful not to cut your fingers by the blades. When the fan rotates at a high speed, the 11 blades will cut the wind ruthlessly like 11 sharp cutting knives. If your fingers enter the cutting range, they will cut ruthlessly. Go down...When the time comes.It is strongly recommended to use it with a protective net.
